GTEs are 10k+ now, so you're probably looking at $20k+ for the swap. Already seen it done on a 3GS so its definitely possible.

Have you ever done an engine swap before?

 

No siiiir never done a swap I'm hands on kinda guy but I'm also willing to pay professionals if I have to, damn bro 20k sheeeeeeesh I might as well let the motor die before I switch it out

 

The swap has been done many times, into GS and IS. The 1jz/2jz are simple engines and do not need much but only 3 or 4 wires to get them to run. That being said, the same can apply to an LS engines. 2jzgte engines are crazy expensive, but you can find 2jzge engines out of an older first gen IS300 and just turbo charge that. But with any jz engine, you will need an aftermarket stand alone computer, injectors, you will need a transmission, clutch, and manually convert the car to standard shift.

As for getting your factory gauges to work thats a huge headache. Most guys just run aftermarket speedo clusters. These kinds of projects take years to build and a lot of money. When you are done you will be kicking yourself at the money pit you sunk into. The car will not be worth much after you are done. Im not trying to scare you, if you have the money by all means go for it. But from someone who has done a jz swap it takes a lot of money. Whatever you price out, double it or triple it. The little parts, fittings, hoses add up real quick.

If this is your daily! I would save up money for something faster, like a GSF or ISF. That way when you go to sell it, you can recoup a lot of your money back when you get tired of it.

 

Thanks I'll keep that one in mind but the devil in me still wanna 2j the **** outta that 350 I mean I kno the resale value won't be great but it'll be a keeper. That's just being hopeful though I'm looking to get a gs460 cuz I do wanna keep the auto tranny

sorry for hijacking the tread but how much work does the engine need to set in the bay ?? is it direct fit or do i have to cut and chop mounts or other stuff??

 

The engine mounts may mount right up, but thats the least of your worries in a swap like this. You can make custom mounts in a day with a welder

 

tell me more whats the hardes part, keep in mind I'm going standalone probably aem infinity or fueltech

 

Where do you live? Theres been a few guys in the middle east who have made this swap in the past.

You will need a 2jz which is super pricey right now, manual transmission, clutch pedal, triple disc clutch, intercooler piping, an fittings, fuel pump, fuel lines, fuel regulator, fuel injectors, fuel meter, fuel rail, wastegate, blow off valve, boost controler, boost gauge, air to fuel meter, oil catch can, tig welding fab work, full custom exhaust from the down pipe onward. Probably most tricky stuff is electronics, trying to get the stock cluster to work and using the rest of the car electronics beside the aem standalone, also you will need to build a seperate engine wiring harness because a 2jz engine is old and so the old wiring goes bad, so a custom engine harness is needed. Then theres the china aftermarket route, where you purchase low quality products and later down the line regret and buy original name brand.

Its a lot of work, a lot of time, if you dont have a lot of money, and or the skill level to work with then I would forget. Because a project like this would sit for years (please dont ask me how I know hahaha). Whatever you think it will cost you multiple it by 2 or 3 times. I dont want to scare you, and also I dont want to see you get stuck which many do and end up parting the cars out.

You would be better off selling the car and trading it for a Lexus GSF with a v8, atleast with the gsf you wont lose as much money. Because when these projects are done and you go to sell the car with a 2jz, it will be very difficult to sell, so it wont hold much money that you threw into it.

Now you have dumped a load of money into the engine, what about the brakes, the suspension. If you think putting a hot rod engine in and not dealing with the rest of the stuff then you will have an unstable car that would be dangerous to drive. Swaps are a huge money pit! If you went with the GSF, it will run better then the 2jz, handle better, brake better, have a better interior. Then when you get tired of it, sell it off.

 

Damn I'm kinda late here but has the 3gs ever been successfully swapped with an LS engine? If so is it a headache or a simple swap. Wouldn't mind a meaty v8 on this car

 

An LS swap would be easier on the wallet, then an JZ. You can buy a cheap wrecked chevy or gmc truck or van and swap the whole lot, that would be on an automatic transmission.

 

I suppose that's true but where I live 2jz or more specifically wrecked 2jz GE/Vvti exist in droves and while the GTE variety isn't as common its is still accessible...cheap. Rn i have the option to buy a GE and an LS engine for around the same price. I'm just wondering if swapping either is gonna be worthwhile or nah

 

Im familiar with the tuner scene in uae, theres a lot of jz's there, but the prices have shot up. The good thing about dubai is theres plenty of used part shops.
